Produkto aprašymas

Ceramic lintel a box for an external roller shutter with a load-bearing capacity dedicated to structural and curtain walls, for internal, protection or anti-burglary purposes. It is made of slotted ceramic fittings with additional thermal insulation that largely eliminates the thermal bridge.

Features

  • the height of the lintels is fixed - 305 mm, and the width is 300, 365, 425, 490 mm
  • all lintels are reinforced at the top and bottom with two steel rods with a diameter of 6 mm each
  • reinforcement integrating the lintel located in diagonal furrows, it is also made of a rod w with a diameter of 6 mm
  • lintels are made of ordinary concrete with a class not lower than B20
  • aggregate grain size in concrete must not exceed 8 mm
  • reinforcing bars made of ribbed steel with a diameter of 6 mm

Application

The product is used for sticking openings in windows and doors, mainly in external walls. Roller shutters installed inside the lintels are an additional closure of the openings in the window or door. The size of the thermal bridge at the lintel is reduced due to the internal space of the lintel, which is additionally insulated with a polystyrene insert.

Technical data

  • the length of the ceramic fittings is 220 mm
  • deviations in the dimensions of ceramic fittings must not exceed 2 mm for dimensions up to 100 mm, 3 mm for dimensions from 101 mm to 200 mm, and 4 mm for dimensions of over 200 mm
  • permissible inaccuracies in the execution of fittings: deviation from the plane of external surfaces of fittings - 2 mm; deviation from the right angle between external surfaces of fittings - 2 mm; deviation from the right angle between the external surfaces of the fittings and the faces - 3 mm
  • fittings absorption cannot be lower than 6% and not higher than 22%
  • mass of the shaped piece in the air-dry condition not greater than 6.0 kg
  • the bending strength (for two fitted fittings) cannot be less than 440 kN
  • fittings subjected to 20 cycles of freezing down to -20 C and defrosting should not show any damage (cracks, scratches, chipping and peeling)
  • plain concrete should have a class not lower than B20; aggregate grain size should not exceed 8 mm
  • for the reinforcement of lintels, ribbed steel bars with a diameter of 6 mm, made of steel A-IIIN class, should be used
  • the permissible deviations in the lintel dimensions are 4 mm wide, 4 mm high, and 10 mm long
  • permissible inaccuracies in the execution of lintels: deviation from the right angle between the base surface and vertical walls of the lintel - 3 mm, deflection of the lintel from the vertical plane - 5 mm, deflection of the lintel from the horizontal plane - 3 mm
  • heat transfer coefficient k [W / m2K]: 0.49 (wall thickness from 24.0 cm
    from 30.0 cm); 0.37 (wall thickness from 36.5 cm to 45.5 cm); 0.25 (wall thickness from 42.5 cm and above)
  • estimated lintel weight per 1 meter: 60 (wall thickness from 24.0 cm to 30.0 cm); 64 (wall thickness from 36.5 cm to 45.5 cm); 67 (wall thickness from 42.5 cm and above)
